Sex-dependent effects of chronic jet lag on circadian rhythm and metabolism in mice.

ABSTRACT:

Background

The circadian clock integrates external environmental changes into the internal physiology of organisms. Perturbed circadian clocks due to misaligned light cycles increase the risk of diseases, including metabolic disorders. However, the effects of sex differences in this context remain unclear.

Methods

Circadian misalignment was induced by a chronic jet lag (CJL) shift schedule (light-on time advanced by 6 h every 2 days) in C57BL/6N male and female mice. Core body temperature and activity rhythms were recorded using a nano tag, and the gene expression rhythms of clock and clock-controlled genes in the liver and adrenal glands were analyzed using qPCR. Glucose metabolism and insulin response were evaluated using glucose tolerance, insulin sensitivity, and glucose
